working on my trans swap needed to remove my exhaust j pipe but due to all this rust it appears I'm gonna have to delay this for a few days how do I get this J pipe off will I need a new one?

bolt and nut in the second pic came completely off the first pic and the bolt still on there is stripped and you see the third one don't know how to tackle that all bolts are stripped and rusted to hell the liquid on there is pb blaster tips?

 

Maybe try heating them up with a torch and quickly cooling them with a wet rag.

 

Yup, mine looks the same lol. Thought about getting a J-pipe until I saw the rust.
Just as Joecop67 said, heat it with a torch. PB does help, but only to an extent. If sockets don't fit. Move to a different size and hammer it in there.
Best of luck

 

Rust monster strikes again!

 

Torch it or cut the bolts/nuts. It won't be easy unfortunately.

 

 

 

I would torch it first and attempt to remove with a breaker bar or impact. If that doesn't work, I would attempt to cut the nut off the bolt in both areas and/or drill it out.

 

If you still have patience left you can take a Dremel with a wire brush and try to knock off enough rust to get the breaker bar seated correctly. Add a length of tube and crank that baby until something happens. Either it gives or it snaps and if you're at the point of cutting might as well try it. One time I had success by hammering a socket onto it. I've also gotten screwed to the point of drilling it out, so you are not alone in your pain.

 

you will have to heat up that bolt so it can be remove.

 

My bolts are the same. Except I gotnit with an impact and likely stripped them. I will likely be cutting the bolts ends at some point. I just wanted my J-Pipe installed

 

kill it with fire!!! At this point you are better off heating it, cutting it off, or taking it to an exhaust shop. Those bolts look really bad

replace it with RV6_P high flow precat and a J pipe of your choice

 

Mine looked like that, I ended up dropping the j-pipe and the whole exhaust. Once it was on the floor I was able to use a cutting wheel to cut the rusted nuts off the 3rd cat side that connects to the exhaust. PITA to remove the whole entire thing on the floor since its quite heavy, but with the help of some spare jack stands it wasn't too bad. Once it was on the floor cutting the rusted bolts was pretty easy if you have access to a cutting wheel, torch or even a dremel with metal cutting disc.
